FIG. 1.

(a) Comparison between experimental and theoretical results for CdS dots; 엯, experimental values from Ref. 3 and Ref. 5; ∎, EPM from Ref. 52; solid line, present work. Small dot radii values have been corrected following the procedure described in Ref. 3. (b) Comparison between experimental and theoretical results for CdSe dots; 엯, experimental values from Ref. 2 and Ref. 5; ∎, EMP from Ref. 54; solid line, present work.

FIG. 2.

(a) Comparison between experimental and theoretical results for CdTe dots; 엯, experimental values from Ref. 5; ∎, TB from Ref. 50; solid line, present work. (b) Comparison between experimental and theoretical results for InP dots; 엯, experimental values from Ref. 8 and Ref. 10; ∎, EPM from Ref. 58; solid line, present work.

FIG. 3.

Influence of effective mass values on theoretical predictions: 엯, experimental values from Ref. 2 and Ref. 5 with ; solid, dashed and dotted lines, present work. Experimental point have been reported in the present figure in order to show that agreement between theoretical predictions and experimental data is little affected by effective mass values in this size range.

(a) Comparison between experimental and theoretical results for CdSe wires and dots; 엯, dots experimental values from Ref. 2 and Ref. 5; ∎, wires experimental values from Ref. 19; ▴, rods experimental values from Ref. 25; solid and dashed line, dot and wire present work; +, CdSe dots in silicate glass, present work. (b) Comparison between experimental and theoretical results for InP wires and dots; 엯, dots experimental values from Ref. 8 and Ref. 10; ∎, wires experimental values from Ref. 23; solid and dashed line, dot and wire present work.
